Why is Time Series Data Important in Epidemiology?

Time series data is essential in epidemiology for several reasons:

Trend Analysis: By analyzing time series data, epidemiologists can identify trends and patterns in disease incidence, prevalence, and mortality rates over time.
Seasonality: It helps in understanding seasonal variations in disease occurrences, which can be critical for diseases like influenza that have a seasonal pattern.
Forecasting: Time series models can predict future outbreaks and help in resource allocation and preparedness.
Intervention Assessment: Evaluating the impact of public health interventions over time, such as vaccination campaigns or social distancing measures.
